The AP series proportional and AT series floating PopTop? actuators incorporate equal percentage flow characteristics. The floating and proportional actuators are designed to be used on the 1/2 to 1- 1/4 in. VM series valves for precise temperature control of fluid flow in heating or cooling applications. Features: Floating model is compatible with any 24 Vac three-wire signal. Proportional model compatible with any 0 to 10 Vdc or 4 to 20 mA controller. Spring return logic is only for emergency power loss. Microprocessor controlled (proportional only). Magnetic clutch to maximize the life of the motor and gear train. Manual operating lever/position indicator facilitates field setup. Easy to use lever terminal blocks. Returns actuator to normal position when power is lost for more than 2 seconds.
